API Documentation Request - Firmware V2.2.12 WebSocket Protocol

[markjapp]

I am developing software to interface with the Dwarf II telescope
via the WebSocket API. I have the following setup:

• Device: Dwarf II
• Firmware Version: V2.2.12
• Connection: WebSocket on port 8082
• IP: 10.195.21.103 (STA mode)

PROBLEM:
My WebSocket connection establishes successfully (HTTP 101 upgrade,
Ping/Pong working), but when I send commands like:
{"cmd":"get_all_feature_config"}

The telescope receives the command (TCP ACK) but never sends a
WebSocket response back.

QUESTIONS:

1. Has the API changed in firmware V2.x compared to V1?
2. Is port 8082 the correct port for V2.2.12? (Community docs say 8080)
3. Do commands require initialization/authentication in V2.x?
4. Can you provide updated API documentation for V2.2.12?

I've confirmed the WebSocket connection works (Ping/Pong successful),
so this appears to be an application-layer protocol issue
